E835 at FNAL: Charmonium Spectroscopy in p̄p Annihilations

E835 studied the properties of the charmonium states formed in pp annihilations. Recent and preliminary results are presented, including new preliminary measurements of χcJ masses and widths (improving the knowledge of fine splitting of P states), a preliminary measurement of ψ(2S) branching ratios, and of the two photon partial width of the χc0.
